Prayer of a man. Vs prayer of a woman, Vs prayer of a child is there a difference?

All prayer is super-important. Nevertheless, our rabbis teach that women, who often get more emotional than men and their prayer is often more from the heart, is accordingly especially strong and effective. Also the prayer of children, who are innocent and not responsible for their sins, have prayers which are innocent, less "tarnished" and more idealistic. Accordingly, I guess us men have to try that much harder to pray properly!
